Go with what you have.

You'll be choked down on head selection or your wallet will pumped up beyond recognition (FUBAR).
You're combo likes a minimum of 195cc's intake breathing and a max of 225 (nice head choice). You're dead on with the squish/quench of your piston and rod combo.
Overlap and off the seat valve timing are great for this set up. Rod length and main cap selection will make this thing pleasant to drive.
Make sure your convertor selection is in the RPM range you want it to be.
Personally, I would go bigger on carb CFM selection, you may find you guys are happy with it, but one step, maybe two, will be something you might be happier. Desktop dynos are fun, to a point, but this thing should go forward as it is and tune accordingly. Watch for proper Air/Fuel ratios. More than enough is a good start point then pull it back for all around use.
